RELATED APPLICATIONS

This application is a continuation of application Ser. No. 15/898,781 filed Feb. 19, 2018, which is a continuation of application Ser. No. 14/995,958 filed Jan. 14, 2016, now U.S. Pat. No. 9,895,491 issued Feb. 20, 2018, which is a continuation of application Ser. No. 13/838,084 filed Mar. 15, 2013, now U.S. Pat. No. 9,242,043 issued Jan. 26, 2016, each of which is hereby fully incorporated herein by reference.

FIELD OF THE INVENTION

The present invention is directed to the remote updating of information and data within portable medical devices, such as infusion devices and related systems, including methods of performing such updates. In some cases, the devices and systems may be used for infusing a medicament, including fluid medicaments such as insulin, into a patient.

BACKGROUND

As the number of patients who are treated with ambulatory medical devices increases, so does the need for a facile and reliable way to update and verify the operation of such systems. Examples of ambulatory medical devices include, e.g., cardiac pacemakers, cardioverter defibrillators, neurostimulators (for treatment of, e.g., Parkinson's Disease, epilepsy, and for pain management) and fluid infusion pumps, such as those for the treatment of chronic conditions such as diabetes. In the case of non-implantable devices such as ambulatory infusion pumps, requesting that a patient send his or her pump to a servicing facility may leave the patient without the same level of care while the pump software, for example, is updated and may become costly when numerous pumps need to be updated. Likewise, sending a skilled service provider such as a field service representative (typically from the device manufacturer) to a user's location to update the software on a pump may be efficient when dealing with a convenient number of pumps in a relatively small location. However, as the number of ambulatory infusion pumps in the field increases, and their usage becomes more wide-spread, administering software updates through visits by a skilled service provider may become cumbersome, time-consuming and costly. Additionally, setting aside the time to meet with a skilled service provider may deter some patients from updating the software on their ambulatory infusion pump.

DETAILED DESCRIPTION

Methods are described for updating an ambulatory medical device, including a portable fluid delivery device such as an infusion pump. The methods include, e.g., verification of the status of the ambulatory fluid delivery device or pump before and after the software update to decrease the likelihood of any unwanted or unintentional delivery of medicament or other errors of malfunctions.

Software Update System for an Ambulatory Medical Device

<figref idref="DRAWINGS">FIG. 1</figref> shows a schematic of an exemplary system embodiment <b>200</b> for safely performing software updates on an ambulatory fluid delivery device, or pump <b>210</b>. The system <b>200</b> includes an ambulatory fluid delivery device <b>210</b> that can administer medicament to a patient <b>205</b>. The system <b>200</b> further includes a sensor system <b>230</b> coupled to the patient <b>205</b>. The sensor system <b>230</b> may or may not be part of the ambulatory fluid delivery device or pump <b>210</b>, and may provide data to the pump <b>210</b>, or to a central computing system <b>220</b> independently, or both.

The fluid delivery device <b>210</b> and/or the sensor system <b>230</b> can be configured to communicate directly or indirectly (such as via an intermediary computing device <b>240</b>) with a central computing system <b>220</b> that is accessible by a caregiver <b>260</b>, such as a physician, nurse, etc. The caregiver <b>260</b> can access patient data from the central computing system <b>220</b>, the patient data being obtained from the fluid delivery device <b>210</b>. In some cases, the caregiver <b>260</b> may react to the patient data by interacting directly with the patient <b>200</b>.

Examples of the types of software updates that may be performed include updates to the fluid delivery device's operating system, the firm ware, the communications protocols, the data encryption algorithms, the user interface, the device log, the device history record, and the like. For the purposes of the present disclosure, the term “software updates” may also include installation of the new software on the fluid delivery device and the removal of software from the fluid delivery device.

Software updates may be initiated by a user, such as a caregiver or a patient, by the fluid delivery device manufacturer or its representative, by the central computing system, or any combination thereof. The caregiver <b>260</b>, if, e.g., properly prompted by the manufacturer of the pump <b>210</b>, for instance, may cause the central computing system to provide software updates to the fluid delivery device <b>210</b> and/or provide care instructions to the fluid delivery device <b>210</b>. Also, another entity, such as a manufacturer, authorized repair organization, distributor, or the like, may direct the central computing system <b>220</b> to provide software updates to the ambulatory fluid delivery device <b>210</b>, either automatically as needed or upon prompting a user. Software updates may also be initiated automatically when the fluid delivery device <b>210</b> connects to an intermediary computing device <b>240</b> that is, in turn, connected to the central computing system <b>220</b>. When an action, such as connecting the fluid delivery device <b>210</b> to an intermediary computing device <b>240</b>, or an entity other than the patient initiates a software update, the fluid delivery device <b>210</b> may require input from the patient or a user before fully executing the software update.

<figref idref="DRAWINGS">FIG. 2</figref> shows a schematic diagram of the sensor system <b>230</b>, which may include a patient status sensor <b>232</b>, such as a glucose monitor. The sensor system <b>230</b> may also include components that permit the sensor system to communicate with the central computing system <b>220</b>, such as a patient sensor receiver <b>234</b>, and a sensor system server <b>236</b>. Systems that may be part of the sensor systems <b>230</b> include, for example, a continuous glucose monitoring system; a patient temperature monitoring system; a blood oxygen saturation monitoring system; a heart rate monitoring system; a blood pressure monitoring system; a patient activity monitoring system; and the like. In addition to sensor systems related to the status of a patient, sensor systems that indicate the status of the ambulatory fluid delivery device may be present. Such sensors may indicate, for example, whether a medicament-containing cartridge is inserted into the ambulatory fluid delivery device, whether infusion lines are connected to a patient, the amount of medicament within the ambulatory fluid delivery device, the operational status of the systems and/or subsystems of the fluid delivery device, including but not limited to the hardware and/or software thereof, and the like.

The fluid delivery device <b>210</b> and sensor system <b>230</b> are configured to exchange the patient data with one another and with the central computing system <b>220</b>. The type of patient data may vary and may include patient status data, such as glucose levels, heart rate, temperature, blood pressure, activity level; as well as delivered medicament data; insulin on board; and personal data (appropriately de-identified for privacy requirements, as necessary) such as patient name, sex, age, weight, and the like. The data exchange can occur directly between the fluid delivery device <b>210</b> and the computing system <b>220</b> or can occur between the sensor system <b>230</b> and the computing system <b>220</b>. The patient data can be used to confirm that any contact between the ambulatory fluid delivery device <b>210</b> and the central computing system <b>220</b> is appropriate and that a software update from the central computing system to the fluid delivery device may be completed safely, as described further below.

Communication between the components of the system <b>200</b> may vary and may include wireless or wired connections and may occur over the Internet. Wireless communication may include any suitable wireless system, such as Bluetooth, Wi-Fi, radio frequency, Zigbee communication protocols, infrared or other optical systems, mobile phone systems, and the like. Wired connections can include telephone line connections, RS22 connection, standard USB and micro-USB connections, firewire connections, proprietary connections, or any other suitable type of wired connection.

Additionally, communication between and/or among the ambulatory fluid delivery device <b>210</b>, sensor system <b>230</b> and central computing system <b>220</b> may be direct or it may be through another device, such as a remote controller or an intermediary computing device <b>240</b>. A remote controller may include a dedicated hand-held remote controlling device, a second ambulatory fluid delivery device, a portable computing device that is configured to communicate wirelessly with the ambulatory fluid delivery device, monitors such as blood glucose monitors (including continuous blood glucose monitors), other suitable devices that allow a user to send instructions to the ambulatory fluid delivery device, or any combination thereof.

The intermediary computing device <b>240</b> may include, for example: a hand-held computing device, such as a tablet, a personal digital assistant, a mobile phone, phone, smartphone, personal digital assistant (PDA), a desktop computer, a laptop computer, and the like. The intermediary computing device may be configured to exchange data with the ambulatory fluid delivery device <b>210</b> through a wireless connection (including optical) and with the central computing system <b>220</b> through the internet via a wired connection. Alternatively, the intermediary computing device <b>240</b> may be configured to exchange data with the ambulatory fluid delivery device <b>210</b> through a wireless connection and with the central computing system <b>220</b> through a wireless connection comprising Wi-Fi, a mobile phone signal, or both. In other instances, the intermediary computing device <b>240</b> may be configured to exchange data with the ambulatory fluid delivery device <b>210</b> and with the central computing system <b>220</b> both through via a wired connection, or the intermediary computing device may <b>240</b> be configured to exchange data with the ambulatory fluid delivery device <b>210</b> through a wired connection and with the central computing system <b>220</b> through the internet or other network via a wireless connection comprising Wi-Fi, a mobile phone signal, or both. The inclusion of another device may allow for a smaller ambulatory fluid delivery device or for the inclusion of another device in the system, such as a sensor system.

The software update may include updates to the operating system, the firm ware, the communications protocols, the data encryption algorithms, the user interface, the device history logs, the device history record, and the like, of the fluid delivery device, as mentioned above. The software update may affect the power usage of the fluid delivery device. Additionally, the software update may improve the communications between the fluid delivery device and any of: the central computing system, sensory systems, intermediary computing device, and the patient. Improvement of communications may include establishing more secure signal pathways, creating quicker signal exchanges, or making messages more concise and understandable by the patient. Software updates may also coincide with hardware updates to the fluid delivery device, including changes to a disposable component of the fluid delivery device, such as a fluid-containing cartridge.

Verification of Ambulatory Fluid Delivery Device Status and Performance

Before and/or after a software update from the central computing system <b>220</b> to the fluid delivery device <b>210</b> is performed, at least a portion of the system <b>200</b> verifies the status of the ambulatory fluid delivery device <b>210</b> such as to verify that the ambulatory fluid delivery device <b>210</b> is in a proper operational state such that the pump will not harm the patient or otherwise malfunction or present problems as a result of a software update. A proper operational state may include one in which the device history logs indicate that the fluid delivery device <b>210</b> has not had deviations from expected performance, such as from expected dosage rates, for a threshold amount of time. It may be that the expected performance may be required to be maintained for the past week, the past month, or the past several months to be considered a proper operational state. The proper operational state may also include a requisite level of charge to be present in a battery or power level to be available from a power source. Free, unobstructed movement of parts of the fluid delivery device may also be required in order for the proper operational state to exist, and certain levels of performance may also be required from the memory, user interface, communications components, sensory systems, and the like in order for the fluid delivery device to be in the proper operational state.

The ambulatory fluid delivery <b>210</b> device participates in verification by sending patient data to the central computing system <b>220</b>. The patient data helps to determine the suitability of the software update for the fluid delivery device <b>210</b> and may include, for example, the device history logs of the fluid delivery device, data regarding the administered doses, the operating system of ambulatory fluid delivery device, user profile information, and any other data that may be used determine whether the ambulatory fluid delivery device is suitable for the proposed software update.

The central computing system sends requests for data both before and after the software update, as well as sending the software update, when the system determines that the software update is compatible with the intended ambulatory fluid delivery device. Both the central computing system <b>220</b> and the ambulatory fluid delivery device <b>210</b> can verify that communication regarding the software update is occurring with a qualified source before transmitting the verification information described above. To verify that communication is occurring with a qualified source, the central computing system <b>220</b> can verify, for example, the serial number or model of the intended ambulatory fluid delivery device. On the ambulatory fluid delivery device end, a password or certificate may be transmitted to aid in verifying the communication source. Other secure processing protocols and/or hardware/firmware/software may be utilized, including encrypted communication protocols, secure processors, etc., as are known in the art may be used as desired between and among the various components and entities described herein.

The software update protocol can trigger, for example, the ambulatory fluid delivery device to confirm with a user that the connection between the patient and the fluid delivery device is in a safe condition with respect to the patient. A “safe condition” may be, for example, that the patient cannot accidentally receive unintentional amounts of medicament. Such conditions may include those when the ambulatory fluid delivery system is not currently administering the medicament, not attached to the patient, when the cartridge is not located within the ambulatory fluid delivery device, when the liquid drug repository not in fluid communication with the patient, when the ambulatory fluid delivery device does not contain any medicament, or any combination thereof. When in the safe condition, the fluid delivery device may display a message to have alternative materials for delivery of the fluid normally delivered by the fluid delivery device on hand for the patient. The fluid delivery device may also display messages for verification of a battery level or a constant power supply prior to proceeding with the software update, as well as warning to disconnect the fluid delivery device from the body of the patient.

A safe condition may be verified in many ways. The ambulatory fluid delivery device may have sensors to verify that a safe condition exists. The ambulatory fluid delivery device may send an inquiry message to a user, such as by presenting a message on the graphical user interface, reciting an audio message, sending a message to an external device, or the like, to confirm that the fluid delivery device is in a safe condition. The ambulatory fluid delivery device may remind the user to maintain the safe condition until after test conforming to the safety protocols have been successfully performed after the installation of the software update. The fluid delivery device may require that a user confirm that the software update should proceed by requiring input from the user that includes the providing a number that is visible on the fluid delivery device only after a portion of the device is disengaged, for example, when a medicament containing cartridge is removed. The number may be a static number, or it may be a dynamic number that is synchronized with a number generator that is also available to the central computing system.

The tests conforming to the safety protocols may vary depending on the device and the nature of the software update. There may be some tests that are always performed by the ambulatory fluid delivery device, such as those tests that are performed after initial construction of the fluid delivery device and upon powering on of the ambulatory fluid delivery device. These self-tests may include those which confirm the software and hardware configuration of the fluid delivery device, confirm that any previously loaded configurations, settings, or other data were not unintentionally deleted, and that confirm that the fluid delivery device performs according to factory initialized, or reset, settings. The self-tests may reset certain values, such as insulin on board (IOB).

Communications between a fluid delivery device and a central computing system may include accessing data through a request sent from the fluid delivery device to the central computing system. Alternatively, communications may include data transfer over a computer network from the fluid delivery device to the central computing system via an uploader application executing at a host device, such as an intermediary computing device, such that the uploader application may authenticate the fluid delivery device, extracts a data log (e.g. device history record) from the authenticated fluid delivery device, and uploads the extracted data log to the central computing system. Additionally, access to data on the central computing system may be controlled such that access is automatically terminated such that an unattended, but previously authorized device, cannot be used to gain access. Such authenticated interactions may be helpful in maintaining the safety and privacy of patients.

More particulars regarding systems for communication between exemplary fluid delivery devices and systems that include a central server (i.e., a network data manager), including those which utilize an intermediary computing device may be found in U.S. patent application Ser. No. 13/564,188, titled, “Therapy Management System,” filed Aug. 1, 2012, the disclosure of which is incorporated by reference in its entirety herein.

Following the installation of software on the ambulatory fluid delivery device <b>210</b>, the fluid delivery device <b>210</b> will conduct tests to verify the data contained on the ambulatory fluid delivery device, as well tests to confirm that the ambulatory fluid delivery device performs according to safety protocols that help to ensure the safety of the patient using the device. Data from the ambulatory fluid delivery device may be redundantly stored, or backed-up, by the central computing system prior to the installation of a software update on the ambulatory fluid delivery device. Such backed-up data may include device history logs; the device history record; user profiles, including basal rate profiles; user information, such as, but not limited to, name, age, sex, location, and care giver information; and the like. After a software update installation finishes on an ambulatory fluid delivery device <b>210</b>, the fluid delivery device <b>210</b> may send the data back to the central computing system for comparison to the backed-up data. This process may assure patients that basal rate profiles and other dosing instructions, as well as other important information, will not be unexpectedly affected by a software update.

An exemplary method of performing software updates on an ambulatory fluid delivery device while the device is in the field includes verification of the ambulatory fluid delivery device status and performance, both before and after a software update occurs. The ambulatory fluid delivery device will be confirmed to be in a safe configuration and will have a performance record that indicates the fluid delivery device is in proper working order before the software update occurs. After the software update occurs, the ambulatory fluid delivery device will be tested and proven to be in working order before being returned to service, dispensing medicament to a patient.

In an exemplary method, a central computing server and an ambulatory fluid delivery device exchange information (such as over the Internet or other computer network) to confirm that a communication interaction is appropriate before taking further action. This may include a confirmation that a secure communication connection is accessible between the two components.

Once it is confirmed that the central computing server and the ambulatory fluid delivery device have an allowable connection, the central computing server verifies that the ambulatory fluid delivery device can appropriately accept a proposed software update and that the ambulatory fluid delivery device is in a safe condition. As discussed above, any of a variety of conditions can be used as criteria for the existence of a safe condition.

The central computing server then sends the software update to the ambulatory fluid delivery device. This can occur, for example, over a network such as the Internet. The ambulatory fluid delivery device, in turn, receives and installs the software update. Prior to installing the software, the ambulatory fluid delivery device may again verify that a safe condition exists.

Upon completion of the software update installation, the ambulatory fluid delivery device performs one or more tests to confirm that it is in proper operating condition. A user, such as a patient or care giver, then places the properly functioning ambulatory fluid delivery device back into service, by, for example, attaching infusion lines to the patient, adding medicament to the ambulatory fluid delivery device, or installing a medicament containing cartridge.

Some embodiments of an infusion system may include a portable infusion device, as described above and a remote commander device. In such an instance, the portable infusion device may include a suitably configured receiver and/or transmitter for communication with an external device such as a remote commander, as well as programming for directing the use of the device; and the remote commander may additionally include a suitably configured receiver and/or transmitter for communication with an external device such as a portable infusion device, as well as programming for directing the use of the device. For instance, the remote commander may include one or more of the functionalities described herein above with respect to the portable infusion device.

For example, the remote commander may include a processor, a memory, a transmitter and/or receiver, an input mechanism, an output mechanism, e.g., a display, a clock, a timer, an alarm, an estimator, and the like. Hence, in certain embodiments, the portable infusion device may include a transmitter that receives commands, e.g., infusion commands, from the processor and transmits the commands (e.g., to a remote commander or vice-versa). Similarly, the remote commander may include a transmitter that receives commands, e.g., infusion commands, from its processor and transmits the commands (e.g., to a portable infusion device or vice-versa). In such an instance, the portable infusion device and/or remote commander may also include a receiver that receives commands, such as remotely/wirelessly generated commands, and communicates the commands to the processor. Accordingly, the remote commander may include the appropriate hardware and software necessary for producing these functionalities in the remote commander, such as that described above with respect to the portable infusion device. The portable infusion device itself or the remote commander may also include programming that includes an initiating command request, whereby the user has to interact with the device, such as by tapping a screen, e.g., on a display of the portable infusion device or remote commander, so as to accept an infusion recommendation before the remote commander signals the portable infusion device and/or before the portable infusion device accepts the command and begins infusion of the fluid.

Some embodiments of the portable infusion device may also include multiple other capabilities in addition to delivering one or more medicaments (i.e., insulin). For example, the portable infusion device may be capable of interacting with a personal computer (PC) for uploading and downloading data, various file types (e.g., JPEG, PDF) and programs. The portable infusion device may also access and send information wirelessly to a PC or other electronic device (e.g., printer, memory storage device). These functions, for example, may be particularly beneficial to a user for sending and receiving information to a physician, or uploading new or upgrading current programs onto the portable infusion device. Furthermore, the portable infusion device may have instructions, or accessible by the user and/or processor for converting information on the device into various file formats, e.g., portable document format (PDF), word processing documents, JPEG, etc., which may be distributed and shared among various electronic devices. The GUI of the portable infusion device assists in improving the usability of at least these capabilities. In addition, some GUI embodiments may be available to a user by downloading a software application onto the user's cell phone and/or PDA, which would allow the user to use their cell phone or PDA as a remote commander to the portable infusion device.
